Water will penetrate

into the transmitter

and cause faulty op-

eration, or loss of con-

trol, and cause a

crash.

Do not fly in the following places:

-Near other R/C flying fields (within

about 3km)

-Near people on the ground, or objects

in the air

-Near homes, schools, hospitals, or

other places where there is a lot of

people

-Near high tension lines, high struc-

tures, or communication facilities

Radiowave interference and obstructions

may cause a crash. A crash caused by

trouble in the R/C set, or the model itself,

may cause death or property damage.

MEANING OF SPECIAL MARKINGS

Pay special attention to the safety at the parts of this manual that are indicated by the

following marks.

Mark Meaning

Do not fly when you are tired,

sick, or intoxicated.

Fatigue, illness, or intoxication will cause a

loss of concentration or normal judgment

and result in operation errors and a crash.

; Prohibited ; Mandatory

Procedures which may lead to a dangerous condition and

cause death or serious injury to the user if not carried out

properly.

Procedures which may lead to a dangerous condition or

cause death or serious injury to the user if not carried out

properly, or procedures where the probability of superficial

injury or physical damage is high.

Procedures where the possibility of serious injury to the user

is small, but there is a danger of injury, or physical damage,

if not carried out properly.

FOR SAFETY

Extend the antenna to its

full length.

If the antenna is

collapsed, the ef-

fective range of

the radiowaves

will become

shorter.

Always test the digital proportional R/C

set before use.

Any abnormality in the digital proportional R/C set,

or model, may cause a crash.

*Before starting the engine, check that the

direction of operation of each servo matches

the operation of its control stick. If a servo

does not move in the proper direction, or op-

eration is abnormal, do not fly the plane.

Check that the transmitter antenna is not loose.

If the transmitter antenna comes off during use, control will be

lost and the model will crash.

Extend to

full length

Test

(In case of a set w/ frequency board)

Do not touch the engine, motor, and speed control

during and immediately after use.

They are hot and will cause a burn.

When turning on the power switch

After setting the transmitter throttle lever to

maximum slow,

1. Turn on the transmitter power switch,

2. Then turn on the receiver power switch.

When turning off the power switch

After stopping the engine,

1. Turn off the receiver power switch,

2. Then turn off the transmitter power switch.

If the power switch is turned

off in the opposite order, the

engine may go to full throttle

unexpectedly and cause an

injury.

*Maximum slow: Direction in which

the engine or motor runs at the slow-

est speed.

When adjusting the digital

proportional R/C set, al-

ways stop the engine, ex-

cept when necessary.

If the engine suddenly goes to high

speed, it may cause an injury.

When flying, always in-

stall the frequency board

to the transmitter an-

tenna.

When the frequency was changed,

also change the frequency board.

NI-CD BATTERY CHARGING PRECAUTIONS

Always charge the nicd

battery before each flight.

If the battery goes dead during

flight, the plane may crash.

Charge the digital proportional R/C nicd

battery with the special charger, or digi-

tal proportional R/C quick charger, sold

separately.

Overcharging may cause burns,

fire, injury, blindness, etc. due to

overheating, breakage, electro-

lyte leakage, etc.

Use the

special charger

Shock

prohibited

Use

prohibited

Penlight

nicd battery

Do not use commercial nicd penlight

batteries.

During quick charging, the bat-

tery holder contacts may over-

heat and damage the equip-

ment, or prevent charging.

Do not short the nicd battery connec-

tor terminals.

Shorting the terminals may cause sparking and

overheating and result in burns or fire.

Do not drop or apply strong

shock to nicd battery.

The battery may be shorted and cause

overheating or breakage and electro-

lyte leakage and result in burns or

damage by chemical mater.

STORAGE AND DISPOSAL PRECAUTIONS

Do not leave the digital proportional R/C set, battery, model airplane, etc.

within the reach of small children.

Touching and operating the digital proportional R/C set, or licking the battery, may cause

injury or damage due to chemical matter.

Do not throw the nicd battery into a fire or heat the nicd battery. Also, do

not disassemble or rebuild the nicd battery. (If using a Nicd battery)

Breakage, overheating, and electrolyte leakage may cause injury, burns, or blindness.

FOR SAFETY

When not flying the model, store the digital proportional R/C set with the

nicd battery in the discharged state. Recharge the nicd battery before the

next flight. (If using a Nicd battery)

If a partially discharged nicd battery is recharged many times, its memory effect will reduce

the flight time substantially and may cause a crash, even if the battery is recharged.

Nicd battery recycling

Used nicd batteries are an important resource. Stick tape over the terminals and take the used batteries

to a nicd battery recycling center. (If using a Nicd battery)

Do not store the digital proportional R/C

set in the following places:

-Where it is very hot (40C/104F or more) or very

cold (-10C/-14F or less).

-Where the set will be exposed to direct sunlight.

-Where the humidity is high.

-Where there is strong vibration.

-Where it is dusty.

-Where there is steam and heat.

Storing the digital proportional R/C set in the places

above may cause distortion and trouble.

If the digital proportional

R/C set will not be used

for a long time, remove

the batteries from the

transmitter and the

model and store them in

a dry place.

If the batteries are left in the trans-

mitter and model, the battery elec-

trolyte may leak out and degrade

the performance and shorten the

life of the transmitter and model.

Nicd battery electrolyte

The electrolyte in the nicd battery is a strong alkali and can cause blindness if it gets in the eyes. If you

get the electrolyte in your eyes, immediately wash your eyes with water and see a doctor. If you get the

electrolyte on your skin or clothes, it may cause a burn. Immediately wash it off with water. (If using

a Nicd battery)

OTHER PRECAUTIONS

Do not get fuel, waste oil,

etc. on plastic parts.

The plastic may melt and fail to

function.

Always use Genuine Futaba transmit-

ter, receiver, servos, FET amp, nicd

battery, and other optional parts.

Futaba is not responsible for damage, etc. caused

by the use of parts other than Genuine Futaba

parts. Use the parts de-

scribed in the instruction

manual and catalogs.

BEFORE USE

Before making any adjustments, learn the operation of the transmitter and the move-

ment of each servo.

CHANNEL 1

RUDDER OPERATION

When the rudder stick is moved to the right, the rudder moves to the right and

the nose points to the right, relative to the direction of flight. When the rudder

stick is moved to the left, the rudder moves to the left and the nose points to

the left and the direction of travel of the plane changes.

AILERON OPERATION

When the aileron stick is moved to the right, the right aileron is raised and the

left aileron is lowered, relative to the direction of flight, and the plane turns to

the right. When the aileron stick is moved to the left, the ailerons move in the

opposite direction.

To level the plane, the aileron stick must be moved in the opposite direction.

When the aileron stick is tilted and held, the plane will roll.

CHANNEL 2

ELEVATOR OPERATION

When the elevator stick is pulled back, the tail elevator is raised and the tail of

the plane is forced down, the air flow applied to the wings is changed, the

lifting force is increased, and the plane climbs (UP operation). When the

elevator stick is pushed forward, the elevator is lowered, the tail of the plane is

forced up, the air flow applied to the wings is changed, the lifting force is

decreased, and the plane dives (DOWN operation).

CHANNEL 3 (only T3FR)

THROTTLE/FLAP/SPOILER OPERATION

The channel 3 can be used for engine control, electronic speed control, flap, or

spoilers.

When the throttle lever is pulled back (low side), the motor is stopped. When

the throttle lever is pushed forward (high side), the motor turns.

Adaptation for some speed controls so that the direction of

operation is opposite (i.e. MC114, MC117):

•Request the adaptation to the Futaba Service Center.

MIXING OPERATION

(when MIX function is turned on)

This mixing is used with V-tail aircraft, delta wings, etc. so that both

channel 1 and channel 2 functions are combined for the two surfaces.

INSTALLATION AND ADJUSTMENT

This section describes the installation method and adjustment method after installa-

tion when installing the receiver, servos, etc. to the plane.

CONNECTIONS

Connection example is shown below.

INSTALLATION AND ADJUSTMENT

CONNECTOR CONNECTION

Insert the receiver, servo, and

battery connectors fully and

firmly.

If vibration, etc. causes a connector to

work loose during flight, the plane may

crash.

RECEIVER VIBRATIONPROOFING

/ WATERPROOFING

Vibrationproof the receiver by

wrapping it in sponge rubber or

some such material. If the re-

ceiver may get wet, waterproof

it by placing it in a plastic bag.

If the receiver is subjected to strong vibra-

tion and shock, or gets wet, it may operate

erroneously and cause a crash.

RECEIVER ANTENNA

Do not cut or bundle the re-

ceiver antenna. Also, do not

bundle the antenna together

with the servo lead wires.

Cutting or bundling the receiver antenna

will lower the receiver sensitivity and

shorten the flight range and cause a crash.

For aircraft, attach the antenna to the top of

the tail.

SERVO THROW

Operate each servo horn over

its full stroke and adjust so that

the pushrod does not bind or is

not too loose.

Unreasonable force applied to the servo

horn will adversely affect the servo and

drain the battery quickly.

SERVO INSTALLATION

Install the servos to the servo

mount, etc. through a rubber

grommet. Also install the servos

so that the servo case does not

directly touch the servo mount

or other parts of the fuselage.

POWER SWITCH INSTALLATION

When installing a receiver power switch to

the fuselage, cut a rectangular hole some-

what larger than the full stroke of the switch

knob and install the switch so it moves

smoothly from ON to OFF.

Also install the switch where it will not

come into direct contact with engine oil,

dust, etc. Generally, install the switch to

the fuselage at the side opposite the muf-

fler exhaust.

INSTALLATION AND ADJUSTMENT

ADJUSTMENTS

The operating direction, neutral position, and steering angle of each servo are

adjusted.

The basic linkage and adjustments of the fuselage conform to the fuse-

lage design drawings and kit instruction manual. Be sure that the center

of gravity is at the prescribed position.

ADJUSTMENT PROCEDURE

Before making any ad-

justments, set the chan-

nel 1 and 2 Servo Re-

versing switches and

MIX switch on the front of the transmit-

ter to the lower (NOR/OFF) position.

However, when using the V-tail or

Elevon mixing, set the MIX switch to

the upper (ON) position.

Turn on the transmitter and receiver

power switches and make the following

adjustments:

1 Check the direction of operation

of each servo.

If a servo operates in the wrong direction,

switch its Servo Reversing switch. (The

direction of operation can be changed

without changing the linkage.)

*Note that the direction of the aileron, V-

ail, or Elevon servo is easily mistaken.

(Page 9)

2 Check the rudder/aileron and el-

evator neutral adjustment and

left-right (up-down) throw.

Check that when trimmed to the center,

the servo horn is perpendicular to the

servo and check the neutral position of

the fuselage control surfaces (rudder/ai-

leron, elevator, etc.). If the neutral posi-

tion has changed, reset it by adjusting

the length of the rod with the linkage rod

adjuster.

When the throw is unsuitable (different

from steering angle specified by the kit

instruction manual), adjust it by changing

the servo horn and each control surface

horn rod .

3 If necessary,

•Adjust the speed control in accor-

dance with its instruction manual.

•Check the flap or spoiler linkage.

4 After all the linkages have been

connected, recheck the operating

direction, throw, etc.

*Before flight, adjust the aircraft in accor-

dance with the kit instruction manuals.

5 Fly the plane and trim each servo.

USING OTHER FUNCTIONS

NON-SLIP ADJUSTABLE LEVER HEAD

The length of the stick lever head can be adjusted.

1 Unlock lever heads A and B by turning

them in the arrow directions.

2 Set the stick to the most

comfortable length and lock

the lever heads by turning

them in the opposite direc-

tion of the arrows.

USING OTHER FUNCTIONS

CHARGING THE NI-CD BATTERY

(If using a Ni-cd battery)

Never plug the special

charger into an AC outlet

other than specified.

TROUBLESHOOTING

REFERENCE

GLOSSARY

The following defines the symbols and terms used in this instruction manual.

Aileron

Control surface at the left and right sides of

the main wing of an aircraft. It usually con-

trols turning of the aircraft.

Channel

Represents the number of control systems.

It can also represent the number of servos

that are operated.

Down

Means down elevator. It is the direction in

which the trailing edge of the elevator is

pointing down.

Elevator

Control surface that moves up and down on

the horizontal stabilizer of an aircraft. It usu-

ally controls up and down.

Linkage

Mechanism that connects the servos and the

fuselage control surfaces.

MIX

Means the mixing function. V-tail mixing,

Elevon mixing, etc..

Modulation method

Two modulation methods are used with ra-

dio control: AM (Amplitude Modulation) and

FM (Frequency Modulation). Another

method that encodes and transmits the

modulated signals is called "PCM".

Neutral

Means the neutral position. It is the state in

which a transmitter stick returns to the center

when not operated.

Normal (NOR)

For the servo reversing function, it is the nor-

mal side. The opposite side is the reverse

side.

Proportional

Because today's radio control sets control

servos in proportion to stick operation, radio

control equipment is called proportional.

Reverse (REV)

With the servo reversing function, this is

used to mean the reverse side. The opposite

side is the normal side.

Rod

A bar that connects the servos and the fuse-

lage control surfaces.

Rudder

Tail control surface that controls the direc-

tion of the aircraft.

Servo horn

A part that is installed to the shaft of a servo

and changes the rotating motion of the servo

to linear motion and transmits the linear mo-

tion to a rod. Servo horns come in various

shapes.

Servo mount

Fuselage base for installing a servo to the

fuselage.

Stick

Rod for operating the transmitter.

Throttle

Part that controls the air mixture at the en-

gine intake. When opened (throttle high

side), a large air mixture is sucked in and the

engine speed increases. When closed

(throttle low side), the engine speed de-

creases.

Trim

A device that fine adjusts the neutral point of

each servo for safe flying. It is a mechanism

that corrects bad tendencies of the aircraft.

Means up elevator. Direction in which the

trailing edge of the elevator is pointing up.
